![]() ![]() It is possible, therefore, that live scallops at these sites are viewed only as food, and the availability of the discarded shells for den building is a fortuitous byproduct. “While large shells could be better materials for den construction, larger scallops also provide a larger meal, and there have been large numbers of shells available at the site for quite a few years now. Some even eat other octopuses, but this is rare. ![]() They mostly diet on fish, shrimp, small crabs, turtles, snails, various crustaceans and scallops, depending on which are available in their environment. “The octopuses at Octopolis harvest the larger scallops among those available,” they explained. Diet and Hunting Methods Octopuses have a large variety of foods in their diet. tetricus is a sentient creature, it’s possible their influence is equally accidental, much as we'd all like to imagine them swimming around with little hammers.Īs Scheel and colleagues explained, it could well be a serendipitous form of engineering in which the octopuses’ natural behaviors and the litter they generate lend themselves well to carving out dens in the environment. It would be a push, obviously, to make out like the fungus had built a city as its influence was unconscious. The fairy-ring-creating Agaricus arvensis fungus was described as an ecosystem engineer for the way it fosters plant and microbial diversity in Mediterranean grasslands. Moray eels enjoy eating octopuses arm by arm and dolphins will toss and thrash an octopus against the water’s surface in an effort to stun them prior to eating. tetricus studies for at college, simply a concept that can apply broadly to any organism that influences its environment. Although a formidable predator in its own right, the soft bodies of squid, octopus, and cuttlefish are delectable meals for other predators. But the octopus has a number of clever ways to defend itself from attack. On the other hand, losing their shells left cephalopods quite vulnerable to hungry predators. Dolphins, sharks, moray and conger eels will all feed on octopuses. This kind of cumulative effect of animals interacting with and changing their environment is an example of ecological engineering. Octopuses could slip into rocky crevices, for example, to hunt for prey.
